Periodic economic dislocations did not curtail rapid U.S. economic growth during the 19th century. New inventions and capital investment led to the creation of new industries and economic growth. As transportation improved, new markets continuously opened. The steamboat made river traffic faster and cheaper, but development of railroads had an even greater effect, opening up vast stretches of new territory for development. Like canals and roads, railroads received large amounts of government assistance in their early building years in the form of land grants. But unlike other forms of transportation, railroads also attracted a good deal of domestic and European private investment. In these heady days, get-rich-quick schemes abounded. Financial manipulators made fortunes overnight, but many people lost their savings. Nevertheless, a combination of vision and foreign investment, combined with the discovery of gold and a major commitment of America's public and private wealth, enabled the nation to develop a large-scale railroad system, establishing the base for the country's industrialization.
